tion proceeds, the invention resides in the construction and arrangementoi' parts, as

hereinafter described and claimed, `it beingunderstood that changes canbe made within 1 the scope of what is claimed, without departing fromthe spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein- IFigure 1 is a side elevation of the improved sash fastener, with the dogin fastening position. l f

Fig. 2 is a plan view of the device with the dog in released position.

F ig. 3 isl a section of the device on the line 3-3 of Fig. 2, v

The sash fastener comprisesa base 7 of suitable metal and size, whichhas apertures 8 to receive screws 9 or other securing elements to fastenthe base on the lower sash 10 of a window, and the base 7 may be readilypositioned with respect to the upper sash when using the device on lowersashes rlie base 7 is provided outer end with a pair of upstanding ears11 between which a dog 12 is mounted for swinging movement on a pivotpin or rivet 13 engaging through said ears 11 and dog, thereby mountingthe dog fory swinging movement toward and away from the upper sash 15,The dog 12 has a tip 14 of rubber or other frictional material, whichmay be secured on the end of the dog in any suitable manner, As shown,the-tip 111 has a stem. 16 fitted within a slot or recess 17 in the dog,although other means of attachment may be used. The tip or frictionmember lll contacting with the upper sash 15 will prevent the dog andupper sash from slipadjacent to its ping relatively to one another bytheV upward movement of the lower sash or the downward movement of theupper sash, sok

that when the dog 12 is in the position shown in Fig, 2, leaning'against the upper sash,v the sashes cannot be moved relatively to oneanother to raise the lower sash or lower the upper sash.

The dog 12 has a finger piece 18 projecting therefrom for convenient-lyswinging the.

-dog by hand.

A spring 19 is provided for holding the dog in either fastening orreleased position. Said spring is a doubled leaf spring, the loop ofwhich embraces a cross member 20 of the base 7 vwhich bridges an opening21 in the basen-and the lower portion of the spring bearson the base 7Aalong .the corresponding edge of the opening 21, as' seen in Fig. 3. Thespring 12 may be readily moved upwardly through thel opening 21 toengage f the member or portion 20, before the base ,e

is secured on the sash, and the terminals of the spring project betweenthe ears 11 below the lower end of the dog, VThelower end of 22 of thedog forms an abutment to seat on the spring 19 when the dog is moved toreleased position, thereby supporting the dog in upstanding position, asseen4 in Fig.

.3, .and Vthe dog has the corner or cam 23 that moves onthe spring 19,under the pivot axis of the dog, so that when the do is swung tovfastening position, as seen in". ig:

1the'upward.pressure on' the corner or cam 23 by the spring 19 Vwillhold the dog against the sash 15, thereby preventing the dog from beingaccidentallyA released, and also preventing the dog from beingdisengaged from fastening relation with the upper sash by a knifeV bladeinserted upwardly between the sashes base, and a doubled leaf springhaving its loop embracing said portion and having its terminalspro]ecting belowsaid dog, the. ldog having an abutment to bear on thespring'or holding the dog in releasedl position andsaid dog having acani to inove on the spring for holding the dog in :tastening position.Y
